Overview The Energy Conversation As we explored in our first edition (July 2008 – December Chevron has been using the information to stay informed 2009) of The Chevron Pulse Report: The State of Online about energy topics that are important to people participating Conversation about Energy Issues, energy is one of the in the online community. most important issues of our time. It shapes the world we live in today and the future that we will share. The online conversation Edelman and Chevron are excited to share the second about energy is robust, diverse, passionate and dynamic, edition of The Chevron Pulse Report with you. This edition evolving alongside the medium itself. examines energy conversation trends that occurred over the 18-month period of October 1, 2008 through March 31, 2010. During the first quarter of 2010, there were 450 million people We also took a closer look at the first quarter of 2010 and on Facebook, approximately 100 million people on Twitter and analyzed how the results differed from the fourth quarter of there were 9.2 million posts* about energy that emerged across 2009. online platforms. Furthermore, from October 1, 2008 through March 31, 2010, there were 30 million posts about energy. The quarterly report is a way to understand and articulate how the online conversation about energy has evolved. Edelman In the summer of 2008, Chevron partnered with Edelman to placed a lot of emphasis on charts that translate the gain a better understanding of the online conversation about conversation into simple visuals, understanding that it is energy topics. Together, Chevron and Edelman identified nearly impossible to represent 30 million conversations in a more than 50 key energy issues and conversation topics. handful of words. Working with Alterian’s SM2 social media monitoring tool, we began analyzing the focus, volume and sentiment of the online Chevron and Edelman hope you find the information conversation about these issues across blogs, discussion interesting and helpful. forums and social networks, including sites such as Twitter, Facebook, YouTube, Vimeo and Flickr. *The term “posts” is used generically to represent a piece of online content, such as a blog post, tweet, photo, video or discussion comment.

Overview Methodology: Scope Scope Edelman conducted a quantitative and qualitative Within these eight issues, we examined 74 subtopics, analysis of the volume and sentiment of the global, ranging in size from a few hundred posts to more than English-speaking online conversation about energy a million. issues from October 1, 2008 through March 31, 2010, focusing on eight major issues within three broad The analysis was conducted on a quarterly* basis. There categories: were six quarters during the18-month period, beginning with 4Q08 and ending with 1Q10. Edelman examined  Energy Resources – Access; Energy Reserves; changes in volume and sentiment for each subtopic for Energy Security each quarter.  Energy and Technology – Energy Efficiency; Technology and Innovation; Alternatives and Renewables  Energy and Environment – Environment, Resources and Policy; Climate Change These three categories were chosen because they were the broadest terms that applied to the most relevant conversations about energy. *Each calendar year is divided into four consecutive three-month periods known as "quarters." The first quarter (1Q) begins January 1 and goes through March 31. The second quarter (2Q) is April 1 through June 30. The third quarter (3Q) is July 1 through September 30. The fourth and final quarter for each respective year (4Q) occurs from October 1 through December 31.

Overview Methodology: Quantitative Analysis Quantitative Analysis of the Conversation Volume The amount of online conversation about energy is vast, Edelman used Google’s Advanced Search features and there is no objective way of measuring precisely how to catalogue blogs, social networks (e.g., Facebook, many posts there are for a given period. Google has MySpace) and social media sites (e.g., YouTube, indexed billions of webpages, but even they could not Flickr, Revver, Vimeo), as well as Boardreader for provide a comprehensive number of pages, posts or discussion forums. Note: Only public Facebook pages comments. Each search engine and social media were indexed, in accordance with the site’s Terms of monitoring tool collects posts a little bit differently. Service. Edelman captured and analyzed enough of the online Using this methodology, 30 million posts about conversation in order to make confident and reasonable Energy Resources, Energy and Technology, and assertions about the volume and sentiment of the Energy and Environment were identified from discussion. Edelman worked with developers to construct October 2008 through March 2010. a series of Julian date searches that pulled information on the number of posts about specific topics over a given Searches were run in triplicate to ensure data integrity. period of time. The searches were built on Boolean The volume also was manually cross-referenced with taxonomies, which were developed and tested for each results pulled by Alterian’s SM2* social media monitoring of the 74 subtopics, in order to reduce or eliminate false tool to determine whether there were inconsistencies in positives in the search results. the relative volume of subtopics in relation to each other. For example, if there were 1 million posts in Google about a topic, but only 500 posts in SM2, this would signal a likely data query error. In such instances, queries would be reconstructed and redeployed. *SM2 is a social media monitoring and analysis tool that tracks and measures online conversations across blogs, forums and social media platforms based on volume, sentiment and influence.

Overview Methodology: Qualitative Analysis Qualitative Analysis of the Conversation Sentiment While the Julian date searches on Google and The items were selected based on topical relevance. Boardreader provide reasonable assurance of the volume They were weighted according to the predominance of of conversations about the issues we examined, neither subtopics in relation to one another so that the sample platform offers the ability to evaluate the sentiment of said reflected the volumes identified in the quantitative conversations. Because we were examining such a analysis. For example, if the subtopic Biofuels made sizable conversation, it would be untenable to manually up 20 percent of the quantitative sample for the rate the tone and sentiment of each of these posts. Thus, discussion of the topic Alternatives and Renewables, the semantic engine of Alterian’s SM2 social media then 20 percent of the qualitative sample for this topic monitoring tool was used to evaluate the sentiment focused on Biofuels. Additionally, the samples were of the online conversation about each issue. weighted by date to reflect individual conversation trends where possible. Edelman is confident in the tool’s native capabilities, but wanted to provide additional assurance that the tool was More than 5,000 posts were pulled to make up the properly rating issue-oriented conversations. These types sample used in the 2008 survey. A team of 10 of conversations can differ in sentiment and tone from conversation analysts manually reviewed the posts consumer- or product-oriented discussions. and scored them on a 5-point Likert Scale for overall sentiment as well as sentiment on specific issues, In August 2008, Edelman conducted a quantitative survey where: of the online conversation about energy issues. This established the relative volume of conversation about 1 = Very unfavorable energy issues over a seven-month period, from January 1 2 = Unfavorable through July 31, 2008. We drew a randomized qualitative 3 = Neutral sample of posts from the larger quantitative pool in order to gain insight into the tone and trends in the conversation 4 = Favorable about these topics. 5 = Very favorable Chevron Pulse Report – 1Q 2010 Edition, October 2008 - March 2010 | Prepared by Edelman © 2010 Chevron Corporation | 6

Overview Methodology: Qualitative Analysis, continued For example, a post that was very favorable about For the purposes of the Pulse Report, SM2 scored Alternatives and Renewables but very unfavorable about 9.7 million posts across 74 subtopics over an 18- Wave Power would be scored “5” for Alternatives, “1” for month period. Comparing this analysis with other Wave Power and “4” overall. The overall score was based evaluations of the online conversation about specific on the general tone of the article; it was not merely an issues, Edelman is confident that this examination average of the individual scores. Further, net sentiment represents one of the most comprehensive analyses of was calculated based on a weighted average of positive online conversation available. and negative sentiment. The analysts also developed a detailed taxonomy of trigger words that signaled why the post was positive or negative in sentiment. This dictionary of more than 1,000 words was combined with SM2’s existing semantic dictionary in order to provide heightened assurance that the semantic engine was properly scoring conversations. Edelman reviewed a sample of the conversations scored by SM2 and is confident in its semantic scoring. This methodology was applied to the evaluation of six previous quarterly reviews of the online conversation about energy issues.
